GEORGE HAUPT, OF MELROSE, MINNESOTA.

SASH HOLDER AND FASTENER.

Specification of Letters Patent.

Application filed April 16, 1909. Serial No. 490,371.

To all whom it may concern:

Be it known that I, Gnonon HAUr'r, citizen of the United States,residing at Melrose, in the county of Stearns and State of Minnesota,have invented certain new and useful Improvements in Sash Holders andFasteners, of which the following is a specification.

This invention has for its object a simple, durable, and effectiveconstruction of sash fastener arranged to hold a window sash securely atany desired position so as to be positively locked against movement fromthe outside when either in a fully lowered or in an intermediateposition.

The invention consists essentially in a cam member carried by the sashand arranged to bind against the j amb of the window casing, and alockingbolt also carried by the sash and operating in correlation to thecam member, the latter being provided with means for engaging thelocking bolt so as to effect the retraction thereof simultaneously withthe movement of the cam member to released position. And the inventionalso consists in certain constructions, arrangements, and combinationsof the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to thefollowing deseription and accompanying drawings in which:

Figure 1 is a perspective View of a window holder and lock constructedin accord: ance with my invention; Fig. 2 is a rear elevation of thedevice with the back or base plate removed; Fig. 3 is a transversesectional View; and Fig. 4 is a detail perspective View of the cammember.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

The operating parts of my improved sash fastener may be embodied in acasing 1 of any desired construction or design, secured to one of thestiles of the window sash. Preferably the casing 1 is formed withapertured ears 2 at the upper and lower ends of its back 3, the saidears being designed to receive screws or other fastening devices bywhich the casing may be secured to the window sash.

The front end of the casing 1 is formed with a rearwardly projectingstud 5 over which the hub 6 of a cam member 7 is adapted to he slipped.The cam member 7 is formed with an eccentric-ally disposed flange 8which is designed to bind against the adjacent jamb of the window casingwhen the cam member is turned in one direction so as to bind the windowsash at any desired elevation, and a handle 9 is secured to the hubportion of the cam member, said handle projecting upwardly through anopening 10 formed in the front of the casing so as to constitute meansfor the manipulation of the cam member, the opposite end walls of saidopening forming stops to limit the movement of the same.

Coactin with the cam member 7 is a locking bo t 11. This is mounted fora laterally sliding movement in a guide channel 12 formed in the casingat one end thereof, said bolt being provided with a finger piece 13which projects through a slot 14: formed in the front of the casing atone end thereof. A spring 15 is coiled around a pin 16 secured to theinner wall of the front of the casing 1, one arm of said spring beingalso coiled around the cam member 7 so as to swing the same into anoperative position, while the other arm projects downwardly as shown andengages the rear end of the locking bolt 11 and forces the sameoutwardly into engagement with any desired notch or keeper 17 formed inthe adjacent jamb of the window frame. The locking bolt 11 is providedwith an upwardly extending arm 18 designed to be engaged by the rear endof the flange 8 upon the movement of the cam member 7 toward thereleased position, the cam member simultaneously effecting theretraction of the locking bolt.

From the foregoing description in connection with the accompanyingdrawings, it is believed that the operation of my improved sash fastenerand lock is obvious.

The spring 15 has a tendency, as is manifest, to force both the bolt 11and the cam member 7 into operative engagement with the adjacent jamb ofthe window casing, whereby the sash may be held at any desired elevationand also obviously locked in any desired position upon the entrance ofthe locking bolt into one of the keepers or notches 17. By turnin thecam member toward the released position, to carry its flange 8 out ofcontact with the adjacent Wall of the jamb, it is obvious that the boltwill also Patented Mar. 29, 1910.

be retracted, and the sash be free to move upwardly or downwardly.

Having thus described the invention, what is claimed as new is:

A sash fastener, comprising a casing, a cam member pivotally mounted insaid casing, a slidable bolt mounted in said casing, a pin secured tothe casing, and a spring coiled around said pin, one arm of said springbeing also coiled around the cam member so as to swing same into anoperative position and the other arm of said spring engaging the rearend of the bolt, the cam member being provided with means for engagingthe bolt and retracting the same by and upon 15 the movement of the cammember toward the released position.

In testimony whereof I atfix my signature in presence of two witnesses.
